To all whom it may concern Be it known that I, WVILL AM ARTHUR, a subject of the King of England, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Registering Devices for Electric-Train Crews, of which the following is a specification.

This invention relates to certain new and useful improvements in registering device for electric train crews, and pertains more particularly to registering devices employed for the purpose of ascertaining the efficiency of not only the motorman, but the conductor as well.

Ithas been heretofore proposed to ascertain the efliciency of the motorman by registering the time of power on, time of braking, coasting, and number of times "of brake operations,.but these factors do not in any way enable the efficiency of the conductor to be ascertained. I

The motorman must complete his run in a certain prescribed time, but if the conductor wastes time by taking too long in opening and closing the door, or in not promptly giving the ahead signal when the passengers have been either let oifor taken on, then the motorman must speed his car up in order to complete the run in the scheduled time. Thi deprives the motorman of the opportunity of coasting and also requires a longer time of brake application, with the result that more current is employed, and the equipment is subjected to greater wear and tear. The increased con-' sumption of power necessarily require a corresponding increase in coal consumption. I I 7 The present invention therefore briefly proposes to provide a register which" indicates. the efficiency of both the motorman and the conductor, or in other words of the crew as distinguished from prior devices which chiefly propose to indicate the efficiency of the motorman alone.

Further and other objects will be later herein set forth and manifested in the course of the following specification.

In the drawings:

' Figure 1, is a side elevation of the invention; showing the same in a case withits front removed;

Fig. 2, is a top plan view, the case being shown in section;

Fig. 3, is a section on line 3-3 of Fig. 2;

Figs. 4, 5 and 6, are fragmentary side elevations, partly in section, showing the parts during their variou stages of operation. 1

In proceeding in accordance with the invention, a suitable clock mechanism 1, is employed, the master gear 2 ofwhich operates a pinion 3 mounted on a shaft 4, the latter being in suitable operative connection with a register?) which will be referred to as the combined register in the following, since it registers the sum of the braking period, the power-on period and the stop period.

A pipe 6 leads from the air brake line and has a cylinder 7 connected thereto within which latter is a plunger 8 having a rod 9 connected thereto; "Rod 9 has a pin 10' at its upper end which engages in the slot 11 of an arml the latter mounted on a suitable shaft 13. A second'arm 14 is also secured to the shaft 13 and carries alight curved leaf spring braking and starting member 15, which latter engages a brake wheel 16 mounted on the balance wheel arbor' 17 of the clock works.

The plunger rod 9 also has an arm 18 rigidly secured thereto, the arm carrying a pin 19 at its outer end, which pin extends through a slot 20 formed in an arm 21 mounted on the shaft 22, of aregister 23, the latter indicating the number of times the brake is operated, by registering each time the brake is operated.

An electromagn'et 24 is suitably connected, as indicated at W, in the circuit S, ofthe usualmotor controller C, so that whenever the motor controller is. operated to close the circuit the magnet will be energized. A hingedarm 25 carriesan armature 26 which latter is attracted upon energization of the magnet, the'free end of'the arm being dis posed so as to be capable of engaging beneath thearm 18 of the plunger rod 9,as shown in Fig. 6. A finger 27 is rigidly secured to the arm 25 and extends upwardly therefrom.

The clock is normally wound but is inac tive during coasting, the parts in this position being indicated in Fig. 3, in which the spring brake 15 engages the brake wheel 16 of the clock works and holds the clock quiescent, the plunger being also in its lowermost position. When the brakes are applied, air entering the cylinder 7 will move the plunger to its uppermost position as depicted in Fig. 45, thereby raising arm 18, and the latter through the pin 19, slot 20 and arm 21 will rotate the shaft 22 of the brake register 23 and register a time of brake applied, on said register.

This upward movement of the plunger causes thespring 15 to move upwardly to the position of Fig. 4, wiping the wheel 16 in its upward movement so as to start the clock. The clock throughout its operation causes the combined register 5 to be actuated so as to register the braking period. WVhen the brakes are released, the plunger drops but is caught by the finger 27, and prevented from completing its down movement, being held in the position shown in Fig. 5, so that the register 5 will continue its movement and register the entire time during which the car stops or remains at a standstill.

WVhen the motor is started, the brakes being OE, and the=parts in the position of Fi 3, the magnet 2st is energized, attracting the armature 26, and moving the partsto the position of Fig. 6, in which position the spring 15 is still prevented from wiping the wheel 16 and stopping the clock, so that as long as the current remains on the register 5 will continue in operation. This upward movement of the-rod 9 is however not sufficient to operate the brake register 23 so that the latter is consequentlynot affected.

When the current is shut off with theparts in the position of Fig. 6, the arm 25 will be released, due to the deenergization of the magnet 24, and the plunger then completes its down movement, bringing the parts to the position of Fig. 3.

It will thus be apparent from the foregoing that whenever the brakes are applied the brake register 23 will be operated once to indicate that the brakes have been operated once. As long as the brakes are kept applied the upper or combined register 5 will be kept in operation because the plunger is kept in its uppermost position of Fig. 3, and will thus register the durationof the bra-king period, and as long as the car remains at a stop the-period of stopping will be also registered on the register 5, because, upon release of the brakes the plunger is prevented from completing its. down movement to stop the clock,due to the parts beincr then in the position of Fig. 5, the eurrent being off. When the current is on the upper register 5, will also register the length of time, since the plunger will be held in-the position of Fig. 6, in which the clock is permitted to remain active. However, as soon as the current is shut off and the brakes are released, then the parts will occupy the position of 3, in which the clock is iiiactive, and the combined or upper register 5, is likewise inactive.

The finger 27 is preferably secured to the arm 25 so as to be readily removable therefrom, so that if desired, the apparatus will register power-on and braking to the exclusion of stopping. To enable power on only to be registered, a valve 30 is placed in pipe 6, so as to allow the air to be out off from the cylinder and to enable the braking period alone to be determined it is merely necessary to remove the armature carrying arm 25.
